A big panic from people 
That may happen to them, especially for small and medium investors who already bought bitcoin at a high price and in the market, there will be a panic sell from them.
But the big investor will be happy to buy bitcoin at that price because the price is lower and they might not see that in the next year.
But after the price reaches the lowest price, sooner or later, the price will bounce and start the rally.
There is not much to say, if bitcoin went that low then the panic will be at max levels, after all it would be fair to think if institutional investors would still hold their coins under that scenario or if such a scenario was created by them as they sold their coins when the price was going down and this forced the price to go down even further, however even during that scenario there will be some buyers willing to take the risk and they will buy bitcoin at that price, expecting for a bull market to come sooner or later.That may happen to them, especially for small and medium investors who already bought bitcoin at a high price and in the market, there will be a panic sell from them.

Likely, institutional investors are still holding their coins and are still buying more bitcoins because they have large funds.
But small investors, some are desperate and sell their bitcoins, while others hope to get the best moment to buy bitcoins at lower prices.
Yes, the risk faced by investors is getting bigger and it is not easy to anticipate it if they can't control themselves and can't analyze it.
